APPARATUS FOR BRUSHIN G FELT I-IAT-BODIES.

not moved along a generator of the conicalholder of the hat body, as hitherto, but is caused to travel overthe surface of the cone in a closed curve on a part of the cone surface, so that the hairs of the hat body are operated upon in all directions and are subjected to a circular brushing action and pointed. V g

In certain mechanical methodsof brushing felt hat bodies, the hairs are brushed flat owing to the brush only performlng a rectilinear movement. This method of op eration, however, has the disadvantage that the fiathairs tend to adhere to one another both when wet and dry, so that when the hat bodies are dyed the hairs adhere to each other in patches, are diflicult to separate and are frequently torn out, resultlng in de-.

terioration of the article. The flat hairs also tend to adhere to each otherwhen the hat is in use and the hat has an imperfect polish. According to the present invention the hairs are brushed around andto apoint, whereby the adhering together of the hairs is avoided. This is effected by the brush acting in all directions on the hairs, instead of in one direction only, thebrush describing an elliptical or oval curve. around a part of the cone support, an oval curve being preferable, with the broad part of the curve directed toward the base of the cone.v The cone support itself isalso rotated, and the hairs acted upon in all directions, are brushed around and pointed so that. they do not tend to adhere to each other when wet. This method also allows of more eflicient utilization of the brush since the brush operates withthe whole of its width, whereas with a brush only moving along a generator of the cone only the center bristles of-the brush are utilized. V

For performing the operation according to my invention, thebrush is arranged on a bar sliding in a guide and moved by an eccentric or the like. The machine is also Specification of Letters Patent.

provided with means for adjusting the height of the cone support for the hat body, and with means for automatically reversing the direction of movement of the brushes and the con-e support and also has a device for automatically stopping the machine after the completion of a predetermined number of revolutions.

The invention is illustrated in the accom panying drawing, which shows a machine for carrying the improved method into effect and in -which Figure l is a front View of the machine partly in section, and Fig. 2 a plan view thereof, also partly in section. Fig. 3 is another sectional plan view of the machine frame showing details. section of the machine. Fig. 5 is a side view of the gear for automatically stopping the machine. Fig. 6 is a longitudinal sect1on of the brush. Fig. 7 shows a detail. Fig. 8 is a longitudinal section of part of the brush actuating gear, and Fig. 9 shows a detail of the gear shown in Fig. 8.

The machine comprises in the main the conical support for the hat body, the brush Fig. 4 is a vertical carrier, and mechanism for automatically" reversing the direction of movement of the machine and for stopping the latter after a predetermined time.

The support 1 for the hat body is mount chain 7 is mounted on sprockets 8, 9, 10 the sprocket 9 on, the spindle 11 driving the brushing device and the reversing gear. The shaft 2 is arranged to slide vertically in the frame 12, and is carried in a foot bearing 13 by two bars 14, which are supported by chains 15 passing over chain-wheels 16 and carrying a balance weight 17. The two chain-wheels 16 are mounted on a shaft 18, which is journaled in the frame and is adapted to be turned with the aid of gearing'19 and .a crank 20, for the purpose of raising or lowering the conical support. The crank is provided with means for locking it, such as a pawl and ratchet wheel or a spring loaded pin arranged to engage in a socket in the frame, and hold the cone sup-y i which are mounted the brushing devices, and.

by the spindle 11, which drives by bevel gear 21, a shaft 22, the latter driving'by bevel gears 23, 24:, two shafts 25, 26, on

from one of which, for instance, the shaft 25., another brush shaft. 80 may be driven.

with the aid of shaft 27 and bevel gears 28' 29.

The shafts 22, 25, 26, 27, and 30 are mounted on an annular frame 31 encircling the'cone support 1-.

On each of the shafts 25, 26 and 30 there- 30, the bow 38carrying the worm-wheel- 3el z is mounted on annular supports 39 oftlie bearings 40, 41, (Fig. 8'),-which takethe weight.

Thebearing 40 is provided with aflange '42 having a curved slot (Fig. 9.) which en--.

ables the bow 38 and consequently the brushing device, to be adjusted for different sizes ofsupports 1.

-The brush carrier comprises a frame 37 in which the brush l?) is inserted, springs 44 being interposed between the brush and frame (Fig. 6) in order to provide the brush with a certain amount of play which is necessary in view of the wooden support 1 tending to warp and loseits shape under the action of the hot water used during the brushing operation; uniform operation of the'brush is thus insured. alsobe held up to its work by weights instead of by thesprings.

revolutions per minute.

The brush frame carries a rod 15 worln ing in a guide 46. The guide lfi is carried by an arm l'T'in which it is free to rotate. As the rod 1-5 is guided at one part and hasto follow the movements of the eccentric, the

brush carrier and brush consequently d scribe an elliptical or oval path wh ch 1n-. sures that the hairs are brushed in all directions.

The eccentric 35 opertions per minute and the shaft 2 about 40 To 'allow of reversing the direction of rotationof the hat'support and brush carrier, worm gearing 49', 50 (Fig. 5) is pro? vided, which is driven from the spindle 11 and is carried by a bracket 51' cast on the stand or otherwise secured, the part ofthe bracket forming thebearing 51 for the shaft 52 of the worm wheel also serving as The brush may The rod 45 alsocarries a pivoted head brush L8, which performs a curved but smaller movement. 7

a'ting the-brushes makes about 20 revolua pivot for a weighted leveri5 3, whichrocks between two steps 54-. ofabelt-fork bar 55. g

The latter is a'i ranged t'o slide horizontally in the arms 56 of the-stand, and is adapted to move the driving 'belt of the machine and theicrossed belt from the fixed-pulley 59 to one of the two loose pulleys '60, 61'.

The weighted lever 53 is moved'by a crank arm (32, which is keyed tofthe end of the worm wheel shaft 52, and as the wormwheel" rotates strikes against an abutment 63 fixed to the weighted lever 'andlmoves the latter-past its vertical. position, whereupon the lever" dropsby gravity and shifts the'belt fork bar.

In order to enable the belt forkto be operated by hand for the purpose of throwing the machine out of gear, one end of the belt" fork bar is linked by a double armed lever 64, and by a bell crank lever-65- connec'tedto. thelatter, tothe rod 66, which'is (Fig. 5).

Parallel to the rod vided at. one end with ahand crank 69, the.

latterworkingover a graduated scale 70.

On the other end of the shaft 68 is mounted a ratchet wheel 71 (F ig; 3) engaged with a pawl lever 72: (Fig. 7). nected by a--link 73 totheilever 55 and is automatically movedafter every second reversalof the belts so that the lever 72 moves the ratchet-wheel and with it the shaft 68 to the extent of one tooth. .FiXed to the shaft 68 is an arm 7 -il,1which moves with the shaft until it arrives iinderneath the rod 66, and abuttmg'against the latter raises'it. If,

then the weighted lever is rocked at thenext shifting of the belts, the said weighted lever. I only moves until the rod engages with its notch the arm 74. In 'thisman-ner thebelt shifting gear is locked, this taking place when both bel'ts'are on the loose pulleys, so that the machine is "stopped; As the arc to bedescri'bed'by the arm 74 is regulated be- The latter is con- 'guided on the frame ofjthe machine and-is provided on' its undersidewithainotch 67 forehand by adjusting theshaft 68' by means i of the crank 69, one is able to adjust the number'of reversals at every operation, or

the period of treatm'entof a hat body.

It will be obviousthat one gearmay .be-

arranged to stop a numberof brushingma chines and one machine can be provided with several sets of: hat bodies with .ap-z
